When some think of Wireless Ethernet and IP solutions for critical applications, they think of delays and latency. This could be farther from the truth with Millimeter Wave radios producing latency in the nanoseconds (not milliseconds).

That's not all to be excited about, these radios produce up to 2.5Gpbs of bandwidth at distances up to 10 miles (16.5km)! You can place them back to back to increase the distance. There available in license free 60Ghz or easy license 70/80 Ghz.

Its time to rethink wireless and low latency with Millimeter Wave radios:

High speed full-duplex Layer 1 transparent transmission up to 2.5 Gbps, for a total aggregated Layer 1 system capacity of up to 10 Gbps.
